COTTON CLEANER, FEEDER, BIND SEPABATOR ELEVJldZfiR.

To all whom it may concern:

Be it known that I, EMILE A. Cannouonn, a citizen of the United States,and a resident of Shreveport, in the parish of Caddo and .State ofLouisiana, have invented a certain new, useful and Improved CottonCleaner,

Feeder, ahd Separator Elevator; and I do hereby declare the following tobe a full, clear, and exact description, such as will e11- able' thoseskilled in the art to make and use the same, reference being had to theaccompanying drawings, forming 'a part of this specification. i

The invention is designed for use with co'tton gins or like machines andits object is to take the cotton directly from the wagons, bins or otherplaces of supply, clean it and feed it directly to the in.

The machine not only removes dirt, trash and other foreign matter andfeeds the cleaned cotton to the gin evenly, but includes within itselfmeans for elevating the cotton from the place of sup ly and carrying itthrough the cleaner to the gin, the sai means including an air draft orvacuum 0011* duit from the place of sup ly through the separator to thegin feedrol and the trash dischar Broa 1y considered the device is madeup of-a practically air tight casing having connected to its top aninlet conduit leading to the place of supply of the cotton and connectednear its bottoih, a suction pipe or conduit having connected thereto afan, pump or other suction creating device. Within. the casing arcregulating feeder rolls, spiked breakers and a cleaning cylinder, therebeing a foraminous partition between these arts and the outlet for theairdrawn thron the device by the suction apparatus. 4. dischargingvacuum cylinder is placed opposite the air outlet and itis soconstructed that it will receive the cotton freed from its trash andforeign matter, and. discharge it directly into the gin while preventingthe ingress of air throughthe openin through which the cotton isdischarged. here are no valves or' obstructions to the passage of theairzfrom the place of cotton sup ly througiintlie apparatus tothe fan orsize 0- gone '06.

In the accompanying drawings: Figural is a front view of the apparatuspartly broken away so as to show the interior construction; Fig. 2 is aside view; and Fig. 3 is a cross sec tion of Fig. 1.

' In the several views of which like charscters indicate like parts themain casing l is provided at the bottom with an outlet Zlcadmg to a fanor other suction device 3.

source of cotton supply, e

thin and is provided with a vertical iorarninous partition 5, preferablymade of Will eauze. This wire gauze partition has at its ower end ahinged section 6 which is error:-

A pipe or conduit 4 leads from the top to a not shown. The

lar in cross section, and opposite this hinged section the casing 3. isprovided with a door 3 for purposes of access. 2 and on the other sideof e partition is the outlet 8 which discharges the cleaned cottonOpposite the outlet directly into the gin. T his discharge outlet is soshaped as to fit the feed inlet or a gin.

The corrugated regulatin and retaining rolls 9 and 10 extend throng thecotton receiving space and rotate in opposite direc tions so as to feedthe cotton throu h the space between them to the breaker rdlls be neath.The shaft of the roll 9 has upon one end the ratchet wheel 11 whichratchet wheel is driven by the pawls 1'3 and carried by the arms 14 and15 pivoted at 16. The arms 14 and 15 are rocked upon the pivot by thelink arms 17 and 1t iivoted at 19 eccentrically upon the end of t eshaft of the upper breaker. .The breaker $20 is a heavy spiked rollsubstantially filling the s ace between the scrcenzi and the wall of t ecasin and is placed directly below the feedin diggers 9 and 19. Thisbreaker is retai ed by. t .e pulley 21 on the outside of the casing. Thebreaker 22 is directly below the roll 20 and is like it, being driven bypulley 23. It is advantageous to use these rolls 20 and 22-, but it isnot necessary.

The cleaning cylinder 24 is mounted in the enlarged lower part of thecasing with its periphery in close proximity to the hing-ed section 6 ofthe screen, the said hinged section extending beneath the cylinder andto the loweredge of the aperture 25 which is oppoof rated from thecotton will be carried oft by the current through the conduit, 2. Nails,

site the cylinder. This cylinder is driven by ulley 29. The vacuumdischarge roller 26 is parallel to the other rollers and is placed in acasing 27 attached to the main casing so hat the aperture 25 opensdirectly thereinto This casing 27 is circular in cross section, exceptfor the inlet and outlet, and the vacuum cy inder is provided withlongitudinal pro jections or blades 28 made of leather or analogousmaterial which contact throughout their length with the cylindricalinterior of the casing 27, thus practically preventing the passage ofair into the casing 1 through the casing 27. Between the blades 28 arethe spikes 29; which catch the cotton thrown against them by thecleaning cylinder 24 and deliver it through the outlet 8 to the gin, notshown. The discharge roller 26 is driven by pulley 30. The frames 31 and32 are attached to the ends of the casing l for supporting the ends ofthe various roller shafts. The openings 33 and 34 are closed bytransparent material so as to afford means for observing the feed of thecotton.

I wish it to be understood that the fan 3 is intended as a diagrammaticre resentation of any form of suction device placed at anypointconnected with the conduit 2, and I wish it to be further understoodthat several casings like that lettered 1 may be connected with a singlesuction device so that several feeders and cleaners may be operated bythat one suction device.

In operation the air being drawn through the apparatus by the suctiondevice 3 draws the cotton from the source of supply through the conduit4: into the upper part of the easing 1- thus rendering unnecessary anyseparate elevating means. The air will act upon the cotton as it fallsfrom the top of the ass-- ing to the rollers 9 and 10 and will carry offa part of the dust andtrash through the screen 5 which extends to thetop. The

rolls '9 and 10 regulate the feed of the cotton I between them and theirspeed of rotation may be controlled as desired. This may be donebyvarying the throw of the pawls.

The rolls 20 and 21 break the bolls, leaves and similar things ledin'with the cotton and the roll 20 preferably rotates at a speed of 150to-175 revolutions per minute.

The rolls 22 and 24 preferably rotate at a speed of 375 to .400revolutions per minute, while the discharge roll 26 rotates at a speedThe, trash and foreign matter sepasticks and other things which are toolarge to pass through the screen or are too heavy to be drawn throughwill fall to the bottom and rest upon the curved portion 6. Access ishad for removing these through the door 7 and the hinged connection ofthe section 6.

sas es It will be noted that the cotton is under the influence of theair current from the time that it is taken from the source of supplyuntil it has gassed through the breakers and cleaner an is freed fromthat influence only as it is taken by the discharge roll Zoand dclivered into the gin.
